Oakdale, CA – Pete Hettinga, managing partner of 3-H Dairy, became the first operator of a Confined Animal Feeding Operation (CAFO) in California to receive a jail sentence for environmental crimes. Hettinga was sentenced following a guilty plea related to the illegal discharge of polluted wastewater into waterways connected to the Tuolumne River and the Sacramento Delta. The case, prosecuted by the Environmental Protection Agency (EPA), highlights a growing federal focus on holding individuals accountable for pollution stemming from large-scale agricultural operations.
Between 1994 and 1998, Hettinga knowingly directed the discharge of significant quantities of organically polluted wastewater and solid waste from 3-H Dairy. This waste consisted of cow urine, feces, and wash water used in dairy operations. The unlawful discharge directly impacted the quality of local waterways, posing a threat to aquatic life and potentially impacting the drinking water supply for communities relying on the Tuolumne River and Sacramento Delta.
Federal prosecutors presented evidence detailing the deliberate nature of the violations. Hettinga was charged with ten counts of violating the Clean Water Act (CWA), specifically 33 U.S.C. § 1319(c)(2)(A), which prohibits the knowing violation of effluent limitations and other CWA provisions. The EPA’s investigation revealed that Hettinga failed to implement adequate waste management practices, choosing instead to illegally discharge pollutants rather than invest in proper containment and treatment systems.
Sentence & Penalties
On March 13, 1998, Hettinga pled guilty to the charges. Judge sentenced Hettinga to six months of incarceration, followed by a 54-month probationary period. In addition to the jail time and probation, Hettinga was ordered to pay a substantial $100,000 fine. Furthermore, as part of the sentencing agreement, Hettinga was mandated to invest $101,000 in improvements to the 3-H Dairy’s infrastructure, aimed at preventing future illegal discharges.
Significance of the Case
This case is considered a landmark victory for environmental enforcement in California. Prior to Hettinga’s conviction, operators of CAFOs had largely escaped jail time for water pollution offenses, often facing only financial penalties. The EPA and the Department of Justice signaled their intent to aggressively pursue criminal charges against individuals responsible for egregious environmental violations, regardless of the industry.
